Making a local scope inside a for loop, into a global scope

Question

I have been searching but I cant get a clear answer. (I am a beginner in javascript and this is a test/practice inside the console) How can I make a local scope within a for loop, a global scope so I can then add it to variable with an array of objects. For Example : I want the user to set how many stars(rating) a movie has inside a variable(prompt) named "stars". Then be able to call it inside the movieDb variable inside the object/array where it says "rating :" ... using the variable stars so it can console log the stars the user inputs along with the other information. Is this allowed or is there a different approach?

 var movieDb =[
  {
    haswatched : "i",
    title : "In Burges",
    rating : stars,
  },
  {
    haswatched : "i",
    title : "Frozen",
    rating : stars,
  },
  {
    haswatched : "i",
    title : "Mad Max",
    rating : stars,
  },
]

for (var i = 0; i < movieDb.length ; i++) {
  var w = prompt("did you watch the movie?")
  if (w === 'yes'){//first IF
    movieDb[i].haswatched = "you have watched";
    var r = prompt("would you like to rate us?");
        if (r === "yes") {//nested in first IF
            var stars = prompt("Enters Stars");
            alert("Thanks for rating & Watching!")
        } else if(r === "no"){ //nested in second IF
            alert("You did not rate, Thanks for watching!")
        }
  }
  else if (w === "no"){ //first ELSE IF
    movieDb[i].haswatched = "you have not seen";
  }
console.log(movieDb[i].haswatched + " " + "\""+movieDb[i].title+"\"" + " -" + movieDb[i].rating);
}'

I think if I understand what you are trying to achieve, this should help ...

var movieDb = [
    {
    haswatched : "i",
    title : "In Burges",
    rating : 0,
  },
  {
    haswatched : "i",
    title : "Frozen",
    rating : 0,
  },
  {
    haswatched : "i",
    title : "Mad Max",
    rating : 0,
  },
];

for (var i = 0; i < movieDb.length ; i++) {
   var w = prompt("did you watch the movie " + movieDb[i].title + "?")
   if (w === 'yes'){//first IF
      movieDb[i].haswatched = "you have watched";
      var r = prompt("would you like to rate us?");
      if (r === "yes") {//nested in first IF
          var stars = prompt("Enters Stars");
          movieDb[i].rating = stars;
          alert("Thanks for rating & Watching!")
      } else if(r === "no"){ //nested in second IF
          alert("You did not rate, Thanks for watching!")
      }
   } else if (w === "no"){ //first ELSE IF
      movieDb[i].haswatched = "you have not seen";
   }
}

console.log(movieDb);
